I think you'd probably need to visit your university library borrow a physics book and read it. especially the bits that refer to wavelength

"One way of visualizing optical depth is to think of a fog. The fog between you and an object that is immediately in front of you has an optical depth of zero. As the object moves away, the optical depth increases until it reaches a large value and the object is no longer visible."

Means air always has optical thickness of 0? I just wonder about the fact that in this forum so many people simulate radiation and the optical thickness seems to be the significant parameter to choose the radiation modell. So there must be a paper where you could get those values. but i dont find anything...why?

anyway in cfx there are a few different radiation models to chose from. the manual has all the information you need to describe how these radiation models work.
